Bosch Dishwasher not running program?

Hello, my Bosch Dishwasher has stopped running it's programs. Whatever setting I put it on it starts pumping water into the machine then stops and does nothing. The drain feature still works. The semi-clear pipe complex, fitted to the outside on the left hand side of the machine, only fills half way. I don't know is this is a problem or not.

I've cleaned all the pipes I can see. Any ideas?
